What we must consider is the impact that a knowledge of reincarnation would have on the world.
Being skeptical by nature I do not presume to know the criteria for karma, I have to figure out what is worth what for myself. Im not sure that the criterial are universal, other than the standard of holding to ones standards - integrity itself.

The battle of Kurukshetra, the message Vishnu gives Arjuna, is not that we must fight knowing the right causes, but that we fight the sake of expending ourselves in faith of a higher meaning we cant comprehend beforehand.

Courage and willingness to self-sacrifice are broadly carried religious virtues, the Gods are reputed to reward such behaviour with a place in the highest halls.Christianity is weird that way, one god who sacrifices himself for all men, ridding mankind in a sense of the ability to sacrifice on their own terms, to freely choose and thus own their divinity, though there remains the choice of the Virgin, the Son, and the Father, and Catholicism provides with an endless host of angels and saints and martyrs which can also be honoured and take the place that once some heathen density would have had in the heart of a lineage.

This is because, there is no definitive proof of reincarnation - the notion of the Identity is lacking; what is it that survives, prevails? Some call it soul, others spirit, essence, but soul, spirit and essence are different things. What is it that survives?
